-## Installation 
+## Installation
+- SSH into PI
+
+### Get repository
 - pull from repository with `git clone https://git.raise-uav.com/Hermes/AutoSyncHost.git`
-- `pip install mido` 
+- Alternatively download directly from page via download zip and extract into a folder.
+
+### Preparation
+Install Python and pip if they are not already installed. You can use the following commands to install them:
+- `sudo apt-get update` 
+- `sudo apt-get install python3 python3-pip` 
+
+### Create Environment
+Navigate to the directory where you cloned the repository. For example:
+- One directory below the AutoSyncHost directorys like `/home/pi`
+- `python3 -m venv AutoSyncHost`
+- `source AutoSyncHost/bin/activate` 
+
+### Install Packages
+- `pip install mido`  
 - `pip install python-rtmidi`
-- `python ashost.py` in folder
+- 'sudo apt-get install libjack-jackd2-dev' (Might be necessary if error occurs)
-- App is running and waiting for a device playing
+
+### Start Program
+- `cd AutoSyncHost`
+- `python ashost.py`
+
+App is running and waiting for a device playing. You need to restart the script if new devices have been connected.
+If oyu got the systemd service running you need to restart the PI.
 
 ## Usage
 - First MIDI device that sends a midi "start" command becomes the host everybody listens to.

 ### Notes
 It is especially interesting for devices that don´t have a physical MIDI port like the OP-Z or OP-1.
 
+### Make it a service
+This will start the script automatically after the pi has started and will restart it.
+
+Create a ashost.service file in /etc/systemd/system
+- `sudo nano /etc/systemd/system/ashost.service`
+
+```
+[Unit]
+Description=AutoSyncHost service
+Wants=network-online.target

+- Save and exit with CTRL -O, Enter, CTRL X
+- `sudo systemctl daemon-reload`
+- `sudo systemctl enable ashost.service`
+- `sudo systemctl start ashost.service`
+- `sudo systemctl status ashost.service`
+
+The status command should show a running service*
